How To get Huawei Unlock code?

Huawei officially doesn't support the unlocking codes after 2018. But with the help of KingoRoot, you can still unlock Huawei bootloader[/URL]. But if you want to use another way then you need to unlock codes which you'll get by following these steps-
You have to go on the Huawei unlocking page.
Then create an account and login successfully.
Now a pop-up notification will come up showing that "I have read and accepted all terms above" just tap the yes box and go to the next.
Now they'll ask for the information of the device, just provide the required information and tap on the submit button.
Once you submit details correctly, Soon you'll get the unique 16 digit bootloader to unlock the password or code for your Huawei device.
Save this code in notes or somewhere safe drive.
By following this way you can get Huawei to unlock codes.
Hope it helps.

MTK ENGINEERING mode

In other mediatek powered devices like realme 6 and redmi devices MTK engineering mode workes fine but not in realme 7 and narzo 20 pro.
You can enter it by typing *#*#3646633#*#* in native dialler. This might be problem because realme introduced Google dialer insted of its conventional dialler.
Apparently you need Settings>“About this device.” then tap “information about the compilation number.” 7 times before the dialler code will work.
The article also says to try several other codes
*#*#889988#*#*
*#22458#*
*#59#
*#*#2846579#*#*
*#110*01#
*#3698741#
*#35789#*
*#*#4636#*#*
*#*#13411#*#*
*#*#7378423#*#*
*#*#3646633#*#*
*#3646633*#
I have not tried this myself - I do not vouch for it
The article also says there's an "MTK Engineering Mode" app on Google Play which can be downloaded
